What if "Haiku" mixes some people who are working with him and some that are not and gets these people to all file chargebacks with paypal after he has removed the money from the account. paypal believes they all are being scammed and refunds their money.

say lebronjames23 sends 5K to Haiku then Haiku drains the account. lebronjames23 would file a chargeback saying he was scammed. Haiku gets the 5K and his partner gets his original amount back.
